Aerobics, Tai Ji Chuan, etc. Aerobic exercise is characterized by low intensity, rhythm, uninterrupted and continuous.
A long time. Cooperate with explosive anaerobic sports, such as weightlifting, running, high jump, long jump and throwing.

Exercise.
The full name of aerobic exercise is aerobic metabolic exercise, which must meet three conditions:
1, the energy required for exercise is mainly provided by oxidized substances such as fat or sugar in the body.
2. Most muscle groups (2/3) participate in sports.
3. Exercise intensity is between middle and low, and the duration is 15-40 minutes or longer.
Relatively speaking, the energy required for anaerobic exercise is supplied by glycolysis system, and oxygen is not needed in the process of energy supply, with high intensity and short duration, and the heart rate during exercise is generally above 170- 180 beats/min. Such as 100-200m sprint and other intense sports are anaerobic sports.
There are many forms of aerobic exercise, such as brisk walking, jogging, doing aerobic exercise, swimming and cycling. Aerobic exercise is more suitable for national fitness. In aerobic exercise, the oxygen inhaled by the human body is 8 times that in a quiet state. Long-term adherence to aerobic exercise can increase the amount of hemoglobin in the body, improve the body's resistance, resist aging, enhance the efficiency of cerebral cortex and cardiopulmonary function, increase fat consumption, prevent arteriosclerosis, and reduce the incidence of cardiovascular and cerebrovascular diseases.
Aerobic exercise can be done according to local conditions and capabilities. Exercise time can be 20-30 minutes or more three times a week; The intensity varies from person to person. Heart rate should be maintained at around 140 beats per minute for people aged 20-30, 120- 135 beats per minute for people aged 40-50, and100-0 for people aged 60.
